question_answer

Neopentyl bromide undergoes dehydro halogenation to give alkene even though it has no P-hydrogen. This is due to:

A)  \[{{E}_{2}}\] mechanism

B)  \[{{E}_{1}}\] mechanism

C)  rearrangement of carbonations by \[{{E}_{1}}\] mechanism

D)  \[{{E}_{1}}Cb\] mechanism

Correct Answer: C

Solution :

Neopentyl bromide undergoes dehydro-halogenation to give alkene even though it has no  hydrogen atom. This is due to rearrangement of carbocation by  mechanism.
